CHmobile Network Coverage in Switzerland
When looking for a new mobile phone plan, price is not the only factor that matters. It is also important to know how reliably the network works at home, while travelling and abroad. This is where CHmobile comes in: The brand was launched by Sunrise and therefore uses the Sunrise mobile network. This gives customers access to affordable mobile plans without having to compromise on one of Switzerland's most powerful mobile networks.
CHmobile was launched as a new Sunrise brand in November 2025. The provider primarily targets price-conscious customers and people looking for an affordable mobile plan.
If you are currently looking for a new mobile phone plan, it is worth taking a closer look at CHmobile's network coverage in Switzerland. Even though the underlying network is provided by Sunrise, reception and available bandwidth can vary depending on your location.
Find the Right Plan on the CHmobile Network – Including Roaming Abroad
CHmobile offers several plans to choose from. Which plan is right for you mainly depends on how much data you need within Switzerland and whether you want to use roaming abroad.
Currently, CHmobile offers plans such as CHmobile Start, CHmobile Flat and CHmobile Plus. Prices and promotional conditions may change. You should therefore always check the current price before signing up.
- CHmobile Flat: Unlimited data, unlimited calls and SMS – Roaming depending on the option
- CHmobile Plus: Unlimited data, calls and SMS – Roaming: 5 GB in Europe, USA, Canada and Turkey
Conditions may change. Check the current offer before signing up.
Roaming is becoming increasingly important for many contracts. CHmobile Plus includes data roaming in certain countries and regions. Additional options may be useful for other destinations. When travelling abroad, you should therefore check exactly which services are included in your chosen plan and where you can surf at no additional cost.
One special feature is that CHmobile supports both a traditional physical SIM card and eSIM. This allows you to activate your mobile phone plan digitally on a compatible device.
CHmobile – Which Swiss Network Do the Mobile Plans Use and What Does This Mean for You?
The answer is simple: CHmobile uses the Sunrise network. CHmobile is therefore not an independent Swiss telecom provider, but a brand whose mobile service is delivered through the Sunrise network. The technical term for this is Mobile Virtual Network Operator (MVNO).
What does this mean for you? When you make calls, send SMS or use mobile data with CHmobile, your phone connects to Sunrise's mobile infrastructure. The CHmobile brand and the underlying network are therefore two different things. Specifically, this means:
- Mobile network: Sunrise
- 4G/LTE: Available
- 5G: Available
- Voice calls: Outgoing calls via the Sunrise mobile network
- SMS: Included within Switzerland depending on the plan
- eSIM: Available
- Swiss customer service: Available through alao 7 days a week
The offers are particularly interesting for users looking for an affordable mobile phone plan without wanting to give up access to a major Swiss mobile network. CHmobile benefits from Sunrise's existing infrastructure.
Sunrise is one of Switzerland's major telecom providers. According to the Swiss Federal Communications Commission ComCom, Sunrise reached more than 99% of the population with 5G at the end of 2025. 4G coverage was also at a very high level.
This gives CHmobile an interesting combination of an affordable price and powerful network infrastructure.
CHmobile Network Coverage – Quality, Availability & Potential Mobile Plan Issues
CHmobile's network coverage essentially corresponds to the coverage of the Sunrise mobile network. CHmobile states that you can expect comprehensive 4G and 5G coverage in Switzerland, including many rural and mountainous regions.
However, very high population coverage does not mean that you will have perfect reception at every single location. The situation can be different inside buildings, underground car parks, tunnels or remote mountain regions.
- Cities and larger towns: Generally very good 4G/5G coverage
- Motorways and major transport routes: Generally good mobile coverage
- Rural areas: Generally good coverage, but local differences are possible
- Mountains and remote valleys: Reception may be more limited depending on terrain and location
- Buildings and basements: Reception can be affected by walls and building materials
- 5G: Depends on location, device and available network technology
Bandwidth can also vary depending on your location. A 5G connection shown on a coverage map therefore does not automatically mean that you will always achieve the maximum possible speed.
If CHmobile shows no network or voice calls do not work, you should first check whether the problem only occurs at your current location. CHmobile recommends, among other things, checking network coverage, briefly switching airplane mode on and off, and restarting your phone. Software, the SIM card and device settings can also play a role.
Wi-Fi Calling can also be helpful for calls. If your mobile reception is weak inside a building, calls can be made over an existing Wi-Fi connection if your device supports the feature.
CHmobile Network Coverage Map in Switzerland – How to Check Your Network
If you want to know how well CHmobile works at your home address, you should not rely solely on general coverage information. The most reliable approach is to check your specific address.
Since CHmobile uses the Sunrise network, you can use the Sunrise network coverage map for your location. The corresponding map allows you to search by location or address.
The Swiss Federal Broadband Atlas also provides information on mobile network coverage in Switzerland. Among other things, it displays 4G and other mobile network data. The information is based on calculations and models and may differ from the coverage you actually experience.
For the most realistic assessment, you should therefore consider several factors:
- Search for your home town or address on the coverage map.
- Check whether 4G and 5G are available.
- Consider whether you mainly make calls indoors or outdoors.
- Check important locations such as your workplace, holiday home or frequently visited areas.
- If you already know of reception problems, a real-world speed or connection test can provide additional information.
The CHmobile network coverage map for Switzerland is therefore particularly useful if you want to know whether the Sunrise network is strong enough at the locations that matter most to you before switching.
CHmobile 5G Coverage – Availability on the Sunrise Network
5G is generally included in CHmobile's mobile plans. You do not have to pay an additional fee to use 5G. The requirements are a 5G-compatible phone and 5G availability at your location.
The advantages of 5G are not limited to higher speeds. Network capacity and latency can also offer benefits compared with older mobile technologies. However, the actual connection speed depends on factors such as location, network load and the device you are using.
Sunrise's 5G coverage is highly developed throughout Switzerland. According to ComCom, Sunrise covered more than 99% of the population with 5G at the end of 2025.
- 5G usage: Included with CHmobile
- 5G coverage: More than 99% of the population according to ComCom, end of 2025
- Maximum speed: Depends on location, device and plan
- 5G-compatible device required: Yes
- Additional cost for 5G with CHmobile: No
So if you are looking for an affordable mobile phone plan with 5G, CHmobile could be an interesting option. The combination of the Sunrise network and 5G is particularly relevant for users who use a lot of mobile data within Switzerland.
Compare Mobile Plans on the CHmobile Network and Save
A low price alone does not make a good mobile plan. The key is the combination of network quality, data volume, voice calls, roaming, contract conditions and customer service.
CHmobile deliberately positions itself in the lower-priced segment. The new Sunrise brand has been available since 2025 and targets customers looking for simple services at an affordable price. At launch, offers were advertised at introductory prices starting from CHF 9.90.
Whether an offer is actually cheap depends on your individual usage. A CHF 9.90 plan can be attractive if you only need a small amount of data, for example. If you regularly travel abroad, however, roaming services may be more important than the monthly price alone. In that case, a plan including 5 or 10 GB abroad may be the better option.
When comparing plans, pay particular attention to the monthly price, the included data volume in Switzerland and abroad, 4G and 5G usage, calls within Switzerland, calls to other countries, roaming and data roaming, the minimum contract term, the cancellation period, one-time activation fees, available additional options, SIM card or eSIM and the quality of customer service.
CHmobile can be an interesting option for Swiss mobile users who want to combine a powerful mobile network with the lowest possible monthly price. If you have specific requirements for international calls, roaming or international usage, you should compare the individual offers more carefully.
Since promotions and discounts change regularly, it is worth making a current comparison before signing up. This allows you to determine whether CHmobile fits your usage habits or whether another plan currently offers better value.
